AUXILIARY wmnows Filed Dec. 16, 1955 United States This inventionrelates to auxiliarywindows such as storm sash or screen sash andparticularly this invention relates to metal framed sash of thischaracter.

Metal framed auxiliary sash of the aforesaid character are oftenconstructed in such a way that the assembly thereof may be made by thehome owner, thus to enable 1 the elements of such sash to be made lup inkits-tobe sold to the home owner who then purchases the requisite screenor glass panel and assembles the same with the various frame elementsthat are provided in the kit. One serious obstacle to themerchandisingof storm sash and :screen kits of the aforesaid characteris that the sizes of windows vary throughout the country on-what mightbe termed a territorial basis. Because of this, akit that is adapted foruse in a large sec-tion'of the Midwest would not be capable ofconvenient use in other territories such as the territories surroundingsome of the larger cities in Ohio or in the territory aroundPhiladelphia, Pennsylvania. The greatest market for storm sash materialsold as kits in the manner above described is found in connection withdouble hung window installations, and according to prior practice it hasbeen necessary to produce different kits for use in different parts ofthe country.

In view of the foregoing it is the primary object ,of the presentinvention to enable storm sash and screen sash to be so constructed thatkits may be provided which will be readily adaptable for use indifferent parts of the country, thus to enable the merchandising of kitsof the aforesaid character to be materially simplified. Morespecifically, it is an object of the present invention to accomplish theforegoing in such a way that the resulting sash will have a neatappearance and will be of sufficient strength to withstand the handlingand use that is required. Further and related objects of the inventionare to accomplish such a wide adaptability in storm sash and screen sashkits by means that are simple in character, which do not involveappreciable increase in the cost of such kits, and which require nocutting and fitting operations by the user.

Other and further objects of the present invention-will be apparent fromthe following description and claims, and are illustrated in theaccompanying drawings, which by way of illustration, show a preferredembodiment of the present invention and the principles thereof, and whatI now consider to be the best mode in which I have contemplated applyingthese principles. Other embodiments of the invention embodying the sameor equivalent principles may be used and structural changes may be madeas desired by those skilled in the art without departing from theinvention.

For :purposes of disclosure the invention is herein illustrated asembodied inwa storm sash 10 that is partially shown in Fig. .1,.andfully'shownin Fig 7 of the drawings, anditwill be noted (that thissash has annpper rail 11, .abottomu-liail 12.andzia.;pair iofside rails13 and and extension pieces E :wl1ich :serve-as, a frame for a panelsuch as a-pane of glass. .15...

Theside' rails .andatheextensions E .are .rnade from a metal such asalumiuumzwhich, in the present case, is extruded t0 th desired form, and:While the present invention may be applied =to=:r,ails,.made indifferent ways and of. difierent cross s'eetionaiforms, I have foundthat the present invention is;partic.ularly adaptable for use withextruded aluminum rail members ofthe cross sectional form shown-in:Eigs.- 3 and 5.5 This. particular cross sectionalform is illustrated.iurmy Prior Patent No. 2,666,598, and the mitered ends, orig-adjacentframe members are securedltogether bycorner bracket and attachment meansdisclosed in the aforesaid patent, certain modifications being made toenable the objectives of the present invention to be fully attained aswill hereinafter be described. Reference is made to the, aforesaid priorpatent for details of structure .andqoperation notspecifically.describedhere- ,in. Auxiliary sash of the aforesaid character may bereadily and easily mounted on doublehung window frames .in the mannerdescribed in my co-pending applicationSerial No. 543,0 5, filed-October27, 19.55.

Thus, asshow-n in detail in Figs. 3 and 5 of the drawings, themetal-extrusion from which the rails and .the

extensions .E areformed comprises an elongated body which in crosssectional form has a front wall 20 with twowal-ls 21 and 22 projectingtherefrom to define what amounts to asecuring groove 23, and spacedinwardly from .the open side of this groove, a pair of ledges 24 and 25extend toward each other so as to define a narrow slot 26.= The ledges24 and 25 and the slot 26-serve to cooperate with the groove 23 toafford what may be termed an undercut fastening groove, while the spaceoutwardly or to the left of the ledges 24 and 25 in Fig. 3 serves toafiord a clearance space within which portions of fastening elementsmaybe located in a protected portion as will be described. The wallmember 21 constitutes -the outer edge of the frame or rail when asash-is assembled, and inwardly of the wall 22, the metal of theextrusion is formed to receive the panel member that is to .be used inthe sash. In the form herein illustrated the sash are to receive glasspanes 15, and therefore parallel walls 27 and 28, are extended in spacedrelation vand at right angles to the wall 22 to afford a glass mountinggroove 30, the inner side wall surfaces of which are preferably serratedto exert a gripping action upon a resilent, U-shaped mounting strip ,31made from rubber or a plastic. This mounting strip embraces the edge ofthe glass pane 15 and supports the pane in a cushioned relationshipwithin the mounting groove 30.

The .ends of the frame elementsor tails are miter-ed, and are securedtogether by corner brackets 35 that are made from metal so as to have arelatively snug fit within will be afforded between the assembledelements.

the arms 35A so that binder head screws 38 may extend through the slot26 and into the threaded openings 36. This positions the head of thescrew 38 in the clearance space outwardly of the ledges 24 and 25, andby tightening the screws 38, the arms 35A of the corner brackets may beclamped firmly against the ledges 24 and 25, with the mitered ends ofthe rails in engaged relation. In this connection it is noted that whenthus tightened, the inner end of the screw 38 is spaced from the wall20.

In ordinary practice, the several rails that are to be used in making anauxiliary sash are cut to selected lengths that are determined by thedimensions of the window frame upon which the sash is to be used, and ahighly advantageous way of merchandising the sash elements is to havethe home owner measure the glass size of the sash upon which he wishesto provide a storm window or screen. Thus, for any particular windowframe, the lengths of the rails for the auxiliary sash may be made inlengths that are mounted in the frame. It is found, however, that therelationship between the frame size and the glass pane size varies indifferent parts of the country. In the major markets of the country thisvariation in width and height of the frame for any particular glass panesize runs slightly more than /2 in each direction, and in order todistribute auxiliary sash kits throughout the country so as to meet thedemands of the various major markets, provision must be made forassembling a particular kit in either one of two sizes, and in someinstances of course additional sizes in the assembled sash will berequired.

Under the present invention this is accomplished in a simple andeconomical manner through the use of the extension pieces E, which aswill be evident in the drawings, are provided in right and left handembodiments for cooperation with the right and left hand ends of therespective rails. In those instances where the frame dimensions are theminimum with respect to the particular glass size, the sash kit may beassembled in the manner illustrated in Fig. 6 of the drawings, or inother words,

without the use of the extension pieces E. If the extension pieces havea longitudinal dimension X, Figs. 2 and 4-, of A., then only one suchextension piece B will be required in association with each of the railsto cover the range of variations that have thus far been encountered.However, an extension piece B may be provided at each end of aparticular rail as shown in Fig. 1 to double the increase in length thatis to be attained in the particular rail. Thus, as shown in Fig. 8, theframe may be made up with an extension piece at each end of the siderails,

or the frame may be made up with an extension piece at each end of twoof the opposite or top and bottom rails. Finally, where the minimumextension is required, such an extension E may be placed at but one endof each of a pair of opposite rails. The arrangement provided by thisinvention thus affords a Wide range of adaptability of storm sash orscreen sash kits.

The extensions E are provided with parallel mitered ends 40 so that anextension may be placed against the mitered end 41 of a rail such as therail 11 in Fig. 2, and the other mitered edge 40 of the extension E willcooperate with the mitered edge 42 of the adjacent rail such as the rail13 of Fig. 2. When the extension is put in this position, the relatedarm 35A extends through the undercut groove 23 of the extension E andextends for a substantial distance into the undercut groove of thealigned rail such as the rail 11 of Fig. 2. When thus related, thefastening screw 38 will be located in the aligned rail such as the rail11, and when the fastening screws of the corner bracket 35 aretightened, the extension E will be held in accurately alignedrelationship, and true mitered joints These corner structures thatinclude the extensions B have been found to possess exceptional strengththat is far beyond the strength necessary to provide a proper sashframe, and the miter joint that is afforded at each end of the 4extension has been found to be unobjectionable from an artisticstandpoint.

The extensions E, being relatively small, may be provided quiteeconomically because they may be made from what would otherwise be scrapmaterial, and since their production requires merely the making ofmitered cuts that are the same as those employed on the main rails,these extensions may be readily produced with great accuracy and at alow cost.

From the foregoing description it will be apparent that the presentinvention enables sash kits to be produced and merchandised throughoutall sections of the country despite variations that are encountered indifferent markets. Under the present invention the assembly of thesekits may be performed without cutting or fitting operations, and theresulting storm sash or screen sash have the requisite strength and areneat in appearance. Through the present invention the stockingrequirements for wholesale and retail distributors have been greatlyreduced, and these objectives have been accomplished without appreciableincrease in the cost in such sash kits.

Thus, while I have illustrated and described the invention in aparticular embodiment, it will be recognized that changes and variationsmay be made within the spirit and scope of the invention.
